Right, I didn't test the VGA output, only LVDS.
Created attachment 102498 [details] [review] Correct patch This is the correct squash of the commits on the mailing list. My system works fine with it.
The patches that solve this on my machine were all merged already. The drm-intel-nightly tree should be fixed. Can you please verify?
(In reply to comment #11) > The patches that solve this on my machine were all merged already. > > The drm-intel-nightly tree should be fixed. Can you please verify? I tried in latest -nightly(2a38e1bcd4dc9523cd723291340226d139bece1b) 10 times, and didn't find this issue.
